FLUID-nisciiiineins.iinvicn. l l p a specification.

This invention relates to fluid discharging devices and has for its primary object to provide a device which may be readily applied to containers for gasolene, petroleum, or other combustible Huids or gases, whereby the fluid may be freely decanted and air automatically supplied to the container so as to thereby prevent suction at the-discharge end'of the emission tube and thus obviate the possibility of an explosion which Vmight otherwise occur when the combustible fluid is poured upon or in proximity'to a fire or llame. y

More particularly my present improvement consists in the provision of a device for the above purpose which in its preferred form embodies a stopper or closure for the opening in the container head, an emission tube extending axially through the closure and having an inlet for the fluid, and a capillary tube extending through the closure along the side of the emission tube and having its discharge end disposed below the fluid inlet of the emission tube.

vWith the above and other objects in View, the invention consists in the improved fluid discharging device as above described, and in the form, construction, and relative arrangement of its several parts as will be hereinafter more fully set forth, illustrated in the accompanying drawing and subsequently incorporated in the subjoined claim.

In the drawing wherein I have illustrated one practical embodiment of the device and in which similar reference characters desig nate corresponding parts throughout the several views, Figure 1 is a longitudinal sectional view showing my improved fluid discharging device applied to the outlet neclrV of a container.

Fig. 2 is a side elevation of the device detached from the container. Y

Referring in detail to the drawing, 5 designates the body of a container and 6 the discharge or outlet neck thereof. While for convenience, I have shown my device applied to this form of container which is in` i .Specification of Letters fatent... i

general use, it will also beapparent as the.`

description proceeds that the adaptation and use of the device is notte be so limited, as it may, with resort to obvious mechanical 'ch-anges, be rendered adaptable to containers vof various other constructions.

As herein shown, the device consists of a plug or stopper 7 which isof conical or tapering form and is preferably formed of rul'iber, cork, or other like material offering high frictional resistance/whentightly en` i gaged with the edgeof the opening in the outlet `neck of the/container. This stopper is suitablyixed to afrusto-conical `body member 8 which projects beyond the larger 4end of the stopper 7 and in the opposite sides of which the resiliently yieldable rods '9 are securely fixed-abone of theirends. These rods at their otherends are adapted for contact with the opposite sides of the outlet neck 6 of the container `and constitute additional means for securely holding the stopper in place. The lower end of the bodymember 8 is formed with an annular flange or bead 10 to prevent ,longitudinal movement of the plug or closure 7 thereon.

An emission tube 11 extends axially through the body member 8 and at its upper end is laterally curved as at 12. A closure cap 13 for this discharge end of the emission tube is attached to the tube by a chain 14 or other suitablev flexible connection. Below the body member 8 the emission tube 11 is provided with a plurality of circularly arranged series of fluid inlet openings 15. The lower end of said tube is closed and adjacent thereto is provided with a drainage opening 16 whereby the fluid remaining in that portion of the tube below the openings 15 may readily drain back into the container.

A capillary tube 17 also extends through the body member 8 alongside of the emission tube 11. Thistube 17 is laterallyprojected at its upper inlet end as indicated at 18, while its lower end, which preferably eX- tends below the lower end of the emission tube 11 is laterally curved as at 19.

In the use of the device as above described, when it is desired to decant the fluid from thecontainer, the latter is tilted in the usual manner, so that the fluid will passthrough the openings 15 into the emission tube 11 and be discharged through the outlet end 12 thereof. As the fluid ows through the outlet openings 15, atmospheric' air in approx- .sion tube, and when the device is used for pouring petroleum, or other combustible fiuidupon a fire, all danger of explosion is eliminated, since the flames will not be'drawn into the tube 11.

From the foregoing description, considered in connection with the accompanying drawing, the construction, manner of opera-v tion, and several advantages of the invention will be readily understood. The device is `of very simple construction, can be easily and quickly lapplied to the container in its operative position, andis efficient and'reliable for the purpose in view. Of course, the plug or closure of frictionmaterial and the resilient rods 9 might be replaced withan ordinary screw cap for engagement upon the threaded neck of a container. Likewise, the openings 15 through which the Huid en- `ters the emission tube might be` otherwise arranged `than as indicated in the drawing,

while thisemission tube, as Well as the air inlet tube 17, can be secured in the closure plug or cap 1n various ways. It is accordingly tobe`understood that while I have herein shown and Vdescribed one practical, embodiment ofthe invention, the device is nevertheless susceptible of many modifications, and I therefore reserve the lprivilege of adoptingall such changes as may be fairly embodied within the spirit and scope of the invention as claimed.

I claim: f

In a fluid discharging device, a closure plug for a container, an emission tube eX- tending laxially through the closure plug and adapted to project into the container, the latter end of the tube being closed and said tube having a plurality of fluid inlet openings in spaced relation to said closed end thereof,

. said. tube having an additional drainage opening adjacent toits closed end and below the series of fiuid inletV openings, and a capillary :tube extending through the closure plug Y alongside of the emission tube and projecting beyondjthe .closed end of the emission .tube Y to deliver air into the containerin approximatelythe same volume as the outflow of the Y fluid.

In testimony that I claim the foregoing as Y I my invention, I have signed my name.
